The Workbook "Pocket Sketching, The Portable Workshop" follows my Basic Workshop with the exercises. It works! If you do the exercises every few pages, you will be amazed with your results. It also has John F. Carlson's easy-to-use color wheel and my tough-but-effective lesson for linear perspective (buildings, roads, etc.) This little book has gems I've distilled over an entire art career. Compact - Portable - Inexpensive
